Description:

I was create a readonly user on a testdb for my new project. There are two
user types at the project: postgres and readonly. The postgres user is
working in my program with admin rights and handling all concepts
(Transactions, Create, Drop, Maintenance etc...) . And I added readonly user
to my project; protect my tables against sql injections. readonly user only
runs SELECT STATEMENTS for reports. But when I test some tables; There is no
protect of my tables against "ALTER TABLE" commands. I think; that is an
importand bug on PostgreSQL. I hope you can add "ALTER" keyword for
"GRANT/REVOKE" command to PostgreSQL The script at the abouve that I used :

With my best regards.
